I'm living in Egypt and my doctor suggested that I use raw honey..He really supported the idea because some other dry eye patient used it and his eyes got way better.
But unfortunately it really stung me when I used it..then it inflamed my eyes like hell and had to go on local steroids for a while. But my doctor still assures that it helped other people. I used to put saline on them (half and half).
It sounded too stupid when he first told me about it, but I felt like I'm tearing after using it, I wouldn't need eye lubricants for couple of hours later..If it didn't get my eyes inflamed I would've used them! Just make sure the honey is natural and clean.
